The h'eddl'e frames.

I Serial usualtreadles 31' being shown in Fig. 1 for that purpose. At their lower ends the picker sticks 18. enter sockets or recesses formed in picker blocks 32 which are slidablymounted in shuttle boxes 33 carried by the lay at the ends of the shuttle race, the shuttle blocks being provided with side flanges riding in corresponding guide grooves in the shuttle box, as shown in Fig. 5. v i i he shuttle 34, which may beof any con-.

struction, so far as the shuttle driving mechanism'is concerned, but which'as hereshown is of the construction covered by mycopending application for Letters Patent fumber 501,481, filed J une 11, 1909, is. driven from the" shuttlebox at one end of the lay, over the shuttling board to the shuttle box at the other end of the lay through the operation of the picker stick thereon, the picker block being forced bv the picker stick against the end of the shuttle to .give it sufi'icient momentum to carry it across the'loom. The inward movement of the picker stick is limited by'its engagement with a cushion post 103 located on the side of the lay, the picker stick being provided with acushion 104 of rubber or other suitable material to engage therewith.

Preferably the lay is swungby pneumatic means under electrical control such as covered by my United States Letters Patent No. 811,012 dated Jan.,80, 1906, but it may be swung by hand or by automatic means.

A plate 71- which 'siipp The shuttling board over which the shuts tle travels is preferably capable (if-swinging into and out of its operative position automatically so as to be outof the way when the blow. is struck by the reed of the lay. Theshuttling board as here shown comprises an angle "iron plate 35'hinged to the lay .beam 30, Fig. 3, and extending from one shuttle box to the other with crank arms 37, Fig. 5, atits ends connected to toggle links 38 engage with -the rollers 40 and swing the shuttling board to its upper or operative position and hold it therednring the dwell of the lay while the shuttle travels therea'c'ross, though'permitting the shuttling board to drop to the position shown in Fig. 3 as soon as the lay swings forward to free the toggle links from the rollers 40. In this manner the shuttling board is swung out of position when the lay strikes its blow so that wire is notstruck by it. .1

is pivotally mounted on the end of the lay and-this is preferably done by means of a screw 99 which may be adjusted from either end, there being a set screw and'slot 100 for clamping the plate in its adjustments. The shuttling" board is given a corresponding adjustment tobring it level with the bottom of the shuttle box by means of a set screw 101 on bracket- 39 which engages a stopon one of thetoggle links 38.

The shuttle 3-; has a central recess in which is pivotally mounted a-bobbin holder 41'carrying'the bobbin 42 and a guide eye 1'3, saidbobbin holder having an extended end which is adapted to engage with the sprirn retracted swinging frame 44, Fig. 9, at eitdier. end of the shuttle in which the he rear members rollers 45 of the shuttle are journaled. Tn

this manner the bobbin holder is locked in either of its operative positionsand at the same time serves to shift the position of the rollersto cause them to stand atan oblique position with relation to the direction of travel of the shuttle, so that the shuttle will travel close to the reed.

Automatic means is provided for swinging the bobbin holder from one position to the other when it arrives at either of the shuttlev boxes to reverse the position of the bobbin so that the larger end thereof may always travel in advance. vThe means by which this swinging operation of the bobbin holder is performed comprises a curved finger 46, Figs: 5, 7, 8 and S), mounted on a shaft 47 which is journaled in a bracket 48 h. .a maewmmahnma 30 v pi otal stud .60.; ":Th movements-01f the I 49 from oneposition to" the other' cai'rie's'the" v spring pressed beneath the shuttl fioox; vsaid curved-fingerbeing-adapted to-travel through an opening in the Bottom of th'elshlittleboxand engag T @s' ewm F gs: and 85%. -5= and c y it from one-operativejposition to- 5 the other, The 'shaft AIhas fixedlion' itjafn arm 49. havin aipin v50 projecting therefromf;

On the return movement of the lay to the position'of dweltthe roller 75 is again engagod'by the cam plate'ffi to return the take up arm 77 to its position shown in dotted lines in Fig. 8, the loop of the weft wire having been d opped thereby to be taken up by the movement of the shuttle when 'itjis thrown to the. other side. The arm 49 forins a convenient means for permitting the curved finger 46 to be drawn by hand when de ired, as for removing the shuttleto replenish thebobbiu. The plate 102'appearing'in Figs. 5. i and 8 is an nppersgnard plate for the shuttle box to keep the shuttle in its proper path. 1

In order to give tension to the warp wires and to feed the fabric'on to the beam 16 as the work progrcsses thc warp beam 11 is provided with a ratchet wheel 82 engaged by a dog 83 which pivotally mounted on a l0\(l.S-lfulcrmned on the loom frame. there also being a \veightedlever 85 fulcrumed on the. loom frame and connected with the lever 34 by means of a link 86. By means of these cmmcctions the. weight of the lever is'utilized to give the dog 83 the tendency to move upwardly and carry the warp beam with it iii-a direction to exert a force upon the warp wires to give them the desired tO-HSlOIL The lever St is also connected to a piston 87 which works in a cylinder 88 mounted on the floor, there being a valve 89 for admitting compressed air from a supply pipe 90 to the upper end of the cylinder through a pipe 91. The'valve 89 has cords 92 connected therewith and extending to the front of the loom, one ofwhich on being pulled serves to open the valve while the other serves to close thevalve. Who-t the valve is opened in this manner the compressed air forces the piston 87 downwardly and thereby counteracts the effect of the weight onlever 85 so as to lower the dog 83 ton'downwardly a chain 93, which is connected with the end of the lever 84 and passes over a pulley 94 on the loom frame and then connects with the dog 83, causes said dog to swing away from the ratchet wheel so that the warp beam will be. free to wind the fabric thereon. The cloth beam 16 is turned by means of a dog 95 mounted on of a ratchet wheel 97 on the beam 16 when the treadle is depressed, there being a pawl '98 engaging theiratchet: .wheel- 97 to .norfmally hold the" beam 16 against turning. Vhen the fabric has been fed onto the beam 16 to the desired extent the valve. 89 is closed by pulling on the other cord 92 and at the time of closing the supply of compressed air to the cylinder it also opens an exhaust for the air contained in the cylinder so that the weight on lever 85"causes the parts to return to their former position. lifting the piston as well as engaging the dog 83 with the ratchetwheel 82 and turning the mined tension is givcnto the warp wires.

mechanism having been described specifi cally it need not be repeated, but briefly stated the shuttle throwing operation, the shuttling board swinging operation, the operation of reversing the bobbin" and the take up operation are effected in the following order. Starting with the lay in the position of dwell, the shuttle having just been received in the shuttle box at one end "and clamped in place'by the clamping lever (33. and having its end lifted from the bottom of the shuttle box as described, the first etl'ect produced is the throwing of the. bobbiii from one position to the other caused by the roller 61 engaging the rear face of cam plate (32, by so doing taking up a .part of the slack of the weft wire left by the shuttle. Then the roller 75 rides oif of the caiu platc T6 and permits the spring to throw the take up arm and-take up the slack in the weft wire and finall clam 1 the same beneath the head of clamp 80 so that a slight tension may be The operation of the several parts. of the and during a further movementof the pisturn when the'cloth beam 16 is turned to 1 '90 a 'treadle 96, which dog engages the teeth warp beam backwardly until the predeter given thereto, and during this time the toggle links have passed off of rollers 40' to permit the shuttling board to drop out of another forward movement thereof without.

its'having come into a position where the mechanism of the resent invention is brought into operative relation. The heddies are changed in he usual manner between the long beat and the short beat of the lay and then the lay is swung rearwardly to the position of dwell. On the rearward movement of the lay the take up arm 77 is returned to its normal position shown in dotted lines in Fig. 8 by the engagement of roller 7 5 with the cam plate '76, the shuttling board is raised to its operative position by the engagement of the toggle links 38 with the rollers 40, the curved finger 46 is re tracted from the shuttle by the roller 61 riding over the front face of cam plate .62, and finally the trip'arm 29 engages the trip pin 30 at that side of the loom at which the shuttle is then located n that said arm 29 is swung to open the valve 23 and admit compressed air to the cylinder 21 to swingthe picker stick and throw the shuttle acrossthe loom upon the shuttling board fromwhich it is received on the other side where the-cycle of operations above described is repeated.

Of course the operation of the various parts is performed simultaneously at both ends of the lay, with the exception of the opening of the air valve, which is only done 7 shuttle is in the shuttle box.

after the throw of the picker stlck at one' at that end of the lay where the shuttle is located, and while these operations at the end of the lay from which the shuttle has 'just been thrown are mostly ineffective, they do no harm, and in fact one operation has its advantages by preventing an accidental throwof the picker stick at, a timewhen no end of the loom to drive the shuttle across the shuttling board the forward movement of the lay begins, and the rollers 61 are swung by engagement with the rear faces of the cam plates 62, the primary result being that the bobbin is reversed at one end of the loom, and incidentally the effectat the other end of the loom is to have the'curved finger e6 rise behind the picker block which has thrown the shuttle and is returning-slowly to its normal position, and so arrest the picker stick near the inner end of its move-- ment so that if the lay should by accident be returned to the position ofdwell after making the first stroke and without the change of the heddlesthe admission cor pressed air to the cyllnder .of said ick'ev stick will find the picker stick nearihe end Immediately of its stnoke. Itwill therefore not be subjected to the severe strain 'of a forcible throw without the shuttle to resist it. ;.'llliS position of the curved finger 46, picker stick, 1s shown 1n Fig. 5.

behind the T he present invention relieves the weaver .of the necessity for drawing off the weft wire at each end of the loom so as to present it in proper position to receive the blow of the lay and furthermore dispense with the necessity for a'weaver being located at each end of the'loom for this purpose, enabling the loom to be operated by one man.

The reversing of the bobbin at eachend of the throw of the shuttle has the advantage of causing the wire to be drawn off thereof in the same relative direction at all times 'and consequently the work is more, uniformly done. 'This result is also contributedr to the automatic mechanical means for taking up the slack and give a slight tension to the weft wire for straightening it.

I desire it to be understood that this invention is not limited to any specificform or arrangementof parts except in so far as such limitations are specified in the claims.
